CLOSING DEVICE.

To all whom it may concern: I

Be it known that I, EDWARD L. Girrono, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented new and useful Improvements in Closing Devices, of which the following is a specification.

This invention relates to a closing device which may beapplied to the upper sash of a window or to the top rail of a screen within the window to close the entrance to the opening formed between the sash or screen when one of the sash is raised and through which flies and other insects gain entrance to the room in which the window is located.

The primary object of the invention is to rovide a closing device of this character in which brackets for connection with a rail of a sash or screen have mounted therein, a roller to extend transversely of the window pane in the lower sash and to be held in engagement therewith by said brackets so that the roller will serve to close the entrance I to the opening formed between the sash or the screen when one of the sash is lowered.

A further object of the invention is to provide the closing device with roller holding brackets and fastening elements for connecting the same witha support which are so constructed that the brackets may be adjusted transversely of the support to cause the roller to force the sash engaged thereby with the parting strips in thewindow frame to prevent rattling of the sash.

With these and other objects in-view, the invention resides in. the novel combination and arrangement of parts, which will be hereinafter described and particularlypointed out in the claims.

The preferred embodiment of the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to the precise details of construction therein shown, as changes, alterations, and modifications, within the scope of the claims may be resorted to when desired.

In the drawing:

Figure 1 is a view in elevation of a portion of a window and showing the improved closing device connected with the upper sash thereof.

Fig. 2 is a vertical transverse section through Fig. 1.

Fig. 3 is a sectional view through a window screen and a portion of one of the sash Specification of Letters Patent.

and showing the improved; closing device connected withthe screen. I

Fig. 1 is a view in elevation of amodified form of the invention. I "26 Fig. 5 is a detailed perspec ive view of one of the attaching brackets. 7 I Like characters of reference denote corresponding parts throughout the I several views in the drawing. 1

Referring nowto the drawing in detail, the letter A designates a portion of a window in the frame 6 of which is mounted to slide a lower sash 7 andan uppersash' 8. A portion of a window screen 9 is shown an ranged within the frame 6 in Figs. 2 and 3 in the drawing. I II I I I I The preferred form of the closing device which is designated in the drawing by the numeral B comprises a roller 10 having 7 pointed terminals 11 and formed from any suitable material, such as wood, or the like, said roller having formed therein spaced and circumferentially extending grooves 12 to permit the roller to be connected with and supported for turningmovement by attach-' ing brackets 13 by means of which the roller may be connected with the lower rail of the upper sash 8 as shown in Figs. 1 and 2 in the drawing. I I

Each attaching bracket 13 is formed'froma single strand of resilient material, such as v I wire, or the like, and has a portion thereof bent to form a hook 14 which serves as a bearing in which may be arranged the reduced portion of the roller 10 "formed-by, one of the grooves 12, said loop having a restricted mouth 15 to permit the roller 10 v to be easily disconnected therewith if the occasion requires, while the remaining portion of the strip is folded upon itself to form an attaching loop 16 having spacedparallel arms 17 between which may be passed the shank of a fastening element 18, such as a the attaching bracket may be removably and adjustably connected with a su port.

When it is desired to apply See preferred form of the invention to the lower rail of the upper sash of a window to close the entrance to the opening formed between the sash when a screen is arranged within and beneath the lower sash of the window, the roller 10 is connected with the attaching brackets 13 and the brackets secured to the lower rail of the upper sash 8 by means of the fastening elements 18 and in such a and by means of which 100 manner that the roller 10 extends transversely of the pane in the lower sash 7 and bears thereagainst with the pointed ends of the roller contacting with the glass retainin putty on the side rails of the sash.

il vhen the improved closing device has been applied to a window as above described, it will be seen that when the lower sash is in raised position as shown in Fig. 1 in the drawing, the roller B will close the entrance to the opening formed therebetween and prevent flies or other insects from gaining entrance to the room in which the Window is located and that through adjustment of the attaching brackets on the lower rail ,of the upper sas 8, the improved closing device will cause the sash to be held firmly in contact with the parting strips on the window frame to prevent rattling of the sash.

It will, of course, be understood that the rollers B are formed from such material as would permit the roller to be cut to fit windows of different widths and that the construction of the device is such that it may be applied to the top rail of a Window screen as shown in Fig. 3 in the drawing if found desirable to close the entrance to the opening formed between the sash and screen when the sash is in raised position.

In the modified form of the invention shown in Fig. 4 in the drawing and designated by the letter C, the roller 20 comprises telescopically connected sections 21 and 22, each of which is provided between its ends with a circumferentially extending groove 23 for receiving a bearing loop on an attaching bracket and with the outer end of each of the sections 21 and 22 provided with an antifriction roller 24 for contact with the glass retaining putty on the side rails of the sash.

members ranged and a roller The modified form of the invention is applied to a window sash or screen in a simi lar manner to that described for securing the preferred form of the invention to these and it will be readily seen with reference to the drawing that when the device is in applied position, the fastening elements 18 may be turned to cause the heads thereon to register 'with the opening between the arms 17 of the attaching loops on the brackets 13, so that the attaching brackets may be readily disengaged from the fastening elements to permit the re moval of the closing device from the sash or screen.

From the foregoing description, taken in connection with the accompanying drawing, it is at once apparent that a closing device has been provided which when applied to a window is highly efiicient for the purpose set forth, and althoughinexpensive' of manufacture, is strong and serviceable when in use.

Having thus described the invention, what is claimed as new is:

1. In a device of the class described a pair of movable closure members parallelly arand engaging the face of the other member, said roller having pointed ends for engaging the inclined part of the face of said other member.

2. In a device of the class described a pair of movable closure members parallelly arranged, a roller having annular grooves therein, clips having portions engaging such grooves the clips to one member with the roller engaging the face'of the-0. 1 61 member.

In testimony whereof I aifix my signature.
